Description

Verfahren und Vorrichtung zur Herstellung von Naphthalin-Warmpreßgut Das bisher bekannte Verfahren zur Herstellung von Naphthalin-Warmpreßgut mit einem Erstarrungspunkt von über 79" benutzt eine statische Preßeinrichtung. Der Preßvorgang geht so vor sich, daß das Naphthalin-Einsatzgut in Kuchen von etwa 5oo mm Durchmesser zusammengepreßt wird, wobei das entweichende Ö1 nur durch den Siebmantel der zylindrischen Preßform entweichen kann. Um zu Warmpreßgut über 790 Erstarrungspunkt zu kommen, muß, wie schon der Name sagt, das Einsatzgut durch Erwärmen auf eine Temperatur von 40 bis 600 angemaischt werden. Nur in diesem Falle gelingt es, den gewünschten Erstarrungspunkt zu erhalten. Arbeitet man bei tieferer Temperatur, dann ist dieser hohe Erstarrungspunkt nicht zu erreichen, da das Begleitöl nicht in genügendem Umfange abgepreßt werden kann. Bei der oben angegebenen erhöhten Temperatur jedoch gelingt die Erreichung des Erstarrungspunktes über 790 deshalb, weil bei der erhöhten Temperatur das Preßöl noch einen Teil Naphthalin gelöst enthält und dadurch besser beseitigt werden kann. Die Arbeitsweise hat aber den Nachteil, daß durch diese mit dem Preßöl abgeführten Naphthalinmengen das Ausbringen an hochwertigem Warmpreßgut herabgesetzt wird.Process and device for the production of hot-pressed naphthalene material The previously known method for the production of hot-pressed naphthalene with a Freezing point of over 79 "uses a static pressing device. The pressing process goes so that the naphthalene feed in cakes of about 500 mm in diameter is compressed, the escaping oil only through the sieve jacket of the cylindrical Mold can escape. In order to get hot-pressed material above 790 solidification point, As the name suggests, the charge must be heated to a certain temperature from 40 to 600 are mashed. Only in this case will it be possible to achieve the desired To get freezing point. If you work at a lower temperature, this is it high freezing point cannot be achieved because the accompanying oil is insufficient can be pressed off. At the elevated temperature given above, however, it succeeds Reaching the freezing point above 790 because at the increased temperature the press oil still contains a part of naphthalene in dissolved form and thus better eliminated can be. However, the method of operation has the disadvantage that this with the press oil The amount of naphthalene removed reduces the output of high-quality hot-pressed material will.

Es hat sich nun ergeben, daß dieser statische Preßvorgang dadurch wesentlich verbessert werden kann, daß der Preßzylinder bei dem Vorgang in Rüttelbewegung gesetzt wird, z. B. indem er auf einen Rütteltisch gestellt wird. Diese Rüttelbewegung bewirkt eine zusätzliche Verdichtung des Naphthalinkuchens, die überraschenderweise dazu führt, daß auch mit kaltem oder fast kaltem Einsatzgut das hochwertige Naphthalin-Warmpreßgut mit einem Erstarrungspunkt von über 790 gewonnen werden kann. It has now been found that this static pressing process thereby can be significantly improved can that the press cylinder in the Process is set in shaking movement, z. B. by being placed on a vibrating table will. This shaking movement causes an additional compression of the naphthalene cake, which surprisingly leads to the fact that even with cold or almost cold feed the high-quality hot-pressed naphthalene material with a solidification point of over 790 was obtained can be.

PATENTANSPRACHE: I. Verfahren zur Herstellung von Naphthalin-Warmpreßgut mit einem Erstarrungspunkt von über 790 durch statische Verdichtung in einer Zylinderpresse unter Erhöhung der Ausbeute, dadurch gekennzeichnet, daß der Preßvorgang bei niedrigerer Temperatur als üblich, jedoch bei gleichzeitiger rüttelnder Bewegung der Preßeinrichtung durchgeführt wird. PATENT LANGUAGE: I. Process for the production of hot-pressed naphthalene material with a freezing point of over 790 due to static compression in a cylinder press increasing the yield, characterized in that the pressing process at lower Temperature than usual, but with simultaneous shaking movement of the pressing device is carried out.
